What else can I help you with?
What is the movement of heated materials upward and the movement of the cooled material downward called?
This movement is called convection. It occurs when heated materials rise due to lower density, while cooled materials sink due to higher density, creating a circulating flow.
What is the rising of earths crust to higher elevations called?
Mountain building
Is Boiling is the maximum temperature a substance can reach?
Boiling is the temperature at which a substance changes from a liquid to a gas. It is not necessarily the maximum temperature a substance can reach, as some substances can be heated to higher temperatures without boiling.
Under which circumstances do waves move faster?
Waves move faster in denser materials due to the increase in the speed of sound. This is because the particles in denser materials are closer together, allowing for quicker transmission of the wave energy. Additionally, waves can also move faster in materials with higher elasticity, as they can propagate more efficiently.
A pure substance boils only at a certain temperature?
Each liquid boils at a different temperature, but the temperature it boils at is called the Boiling Point. For example, the boiling point of water is 212 Fahrenheit.This specific temprature is dependant on the pressureon the liquid at that time, as an example at ahigher temperatures the boiling point is higher.
What is the movement of materials from a higher to a lower concentration?
The movement of materials from a higher concentration to a lower concentration is called diffusion. This process occurs spontaneously to reach equilibrium, where the concentration of the substance is the same throughout the system.
Materials of low mass are fused together to form a substance of higher mass during what?
During nuclear fusion, atoms of low-mass materials (such as hydrogen) combine to form a substance of higher mass (such as helium). This process releases large amounts of energy in the form of light and heat. It is the reaction that powers the sun and other stars.
Is the density higher or lower when the particles are closer in a substance?
The density is higher when the particles are closer together in a substance because there is more mass packed into a given volume. This leads to a higher mass per unit volume, which is the definition of density.
What is a Diffusion is the movement of a substance?
diffusion is the movement of materials into cell membranes when the outside of the cell has a higher density than the inside
Does an increase in pressure results in a higher melting temperature of a dry substance?
yes because it stays together
Why sample has higher specific gravity?
A sample may have a higher specific gravity compared to other samples due to its composition of heavier materials such as metals or minerals. Specific gravity is a ratio of the weight of a substance to the weight of an equal volume of water, so materials with higher density will have a higher specific gravity.
What is the cell process called when a higher concentration of substance is outside the cell?
Exo-osmosis
When using the particle model of matter to describe what happens to the density of a substance when it cools?
The density of the substance becomes higher because of the particles slow down and move closer together when the substance cools.
What is a sentence for solubility?
Salt in water is an example of solubility.
What is the relationship between molecular weight and density in a substance?
The relationship between molecular weight and density in a substance is that generally, substances with higher molecular weights tend to have higher densities. This is because heavier molecules are more tightly packed together, leading to a higher mass per unit volume, which results in a higher density.
What is low pH and what happen to meat?
The lower the pH of a substance, the more acidic it is. Materials with higher pHs are more basic.I cannot answer the meat portion of this question.
Does a higher number of conducitvity mean is conductive?
Yes, the higher the conductivity concentration the higher the conductivity value in the material. Some times the conductive particles are surrounded with insulating materials which cut the conductive paths between the electrodes and as a result it stops the increase in the conductivity values to a certain limit according to the structure (texture) in the material.
